SACROCOCCYGEAL TERATOMA
Sacrococcygeal teratoma is the most common tumour of the fetus and neonate, with a reported incidence of 1 in 35,000-40,000. This neoplasm is composed of tissues from all three germ layers. The extent of sacrococcygeal teratoma was classified according to the American Academy of Pediatrics.
Type 1 – Primarily external and has only a mimimal presacral component.
Type 2 – Primarily external but has a significant intrapelvic portion.
Type 3 – Partially external but is predominantly intrapelvic with abdominal extension.
Type 4 – Located entirely within the pelvis and abdomen.
Associated complications :
· Intrapelvic mass effect- bladder displacement, hydronephrosis, large tortuous ureters and urinary ascites.
· Dysplastic changes in kidney.
· Severe oligohydoamnios.
· Congenital hip dislocation.
On MRI the content of teratomas can be well assessed. They may be solid, cystic or mixed with areas of necrosis, haemorrhage, and calcification. Predominantly solid masses have a poorer prognosis than cystic avascular masses.
